I can't say I have a better-best preference. Different projects have different goals and budgets. I can say I'm continually impressed with these diyAudio member projects. I do like the well-crafted "solid-state in vacuum tube clothing" aesthetic of the project you linked. But other diy amps, loudspeakers, boomboxes, turntables impress me no less.
